Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of water meter manufacturing, in particular to a stamping ultrasonic meter case. Background Art
[0002] Ultrasonic water meter is a new type of water meter, which detects the propagation time of ultrasonic waves between two transducers and calculates the water flow rate. It is widely used because of its accurate flow calculation.
[0003] However, the shell structure of current ultrasonic water meters is relatively complex, and multiple reflections will be formed inside. In addition, the complex internal structure may also cause clogging of the wires with filaments, thereby affecting the collection of ultrasonic signals and further affecting the accuracy of flow calculation.
[0004] Therefore, how to design and implement an ultrasonic meter case with a simple structure and accurate flow calculation becomes a technical problem that needs to be solved. Utility Model Content
[0005] The purpose of the utility model is to provide a stamped ultrasonic watch case in order to overcome the defects of the prior art.
[0006] The purpose of the utility model can be achieved through the following technical solutions:
[0007] A stamped ultrasonic watch case, the ultrasonic watch case comprising a square tube-shaped watch case body; the watch case body is composed of an upper base plate, a lower base plate and two side plates which are stamped and then welded; the two sides of the watch case body are symmetrically stamped to form reflective bevels which are bent at 45 degrees to the watch case body; the ends of the reflective bevels on both sides are respectively provided with circular water inlets and water outlets; transducer bases for mounting transducers are provided above the reflective bevels on both sides; the two transducer bases are symmetrically arranged.
[0008] Furthermore, the ultrasonic watch case is made of stainless steel.
[0009] Furthermore, the water inlet and the water outlet are pipes that are welded to the ultrasonic watch case after being stamped.
[0010] Compared with the prior art, the utility model has the following advantages:
[0011] (1) The utility model reflects the ultrasonic wave twice through the 45-degree reflection bevel edges symmetrical on both sides. The reflection surface reflects through the tube wall, which simplifies the structure. The distance between the two transducers is longer, the signal time difference is longer, and the accuracy is higher. Moreover, there are no other parts inside the case, so when there are similar linear objects in the water, no threads will be hung, which will affect the sound wave collection, further improving the accuracy.
[0012] (2) The ultrasonic meter case of the utility model is formed by stamping and welding of stainless steel plates, which has a simple structure, is easy to form, and saves costs. BRIEF DESCRIPTION OF THE DRAWINGS

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0018] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.
[0019] In the description of the present utility model, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, or are the directions or positional relationships in which the utility model product is usually placed when in use. They are only for the convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present utility model.
[0020] It should be noted that the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features.

[0022] Example
[0023] like Figure 1 As shown, a stamped ultrasonic watch case comprises a square tube-shaped watch case body 1, which can install a transducer base 5 without punching out a square platform, thereby facilitating manufacturing; the watch case body 1 is composed of an upper base plate 6, a lower base plate 7 and two side plates 8 which are stamped and welded, and the manufacturing material is stainless steel material, with a simple structure and low manufacturing cost; the watch case body 1 is symmetrically stamped on both sides to form a reflective bevel 2 which is bent at 45 degrees to the watch case body 1; the ends of the reflective bevel 2 on both sides are respectively provided with a circular water inlet 3 and a water outlet 4, which are pipes welded to the ultrasonic watch case after stamping; a transducer base 5 for installing the transducer is provided above the reflective bevel 2 on both sides; the two transducer bases 5 are symmetrically arranged.
[0024] The utility model installs transducers on two transducer bases 5, the distance between the two transducers is long, the signal time difference is longer, and the accuracy is higher. The ultrasonic signal emitted from one transducer reaches the other transducer after being reflected by the 45-degree bent reflection bevel 2, and is directly reflected by the pipe wall. The structure is simplified, the ultrasonic loss is small, the accuracy is high, and there are no other parts in the ultrasonic meter case. Therefore, when there are similar linear objects in the water, no threads will be hung, which will affect the sound wave collection, thereby further improving the calculation accuracy of the water flow.
